Can't install the latest trival version of true image echo server for linux!

I download from acronis website.when i try to install it on my redhat as 4 server.To the second screen.I put some information in * field and click next.it prompt:cannot resolve Acronis registration site address.

I also download the Acronis True Image Echo Enterprise Server trial version.
I have no problem install into Windows XP.
Then, I created the agent for linux and try install in Fedora Core 6, but prompt at registration screen,
Can't resolve Acronis regsitration site address.

How can I resolve this problem? Or can I get the trial version without the registration screen. Thanks

Could you please create a screen shot of the registration screen that appears?
